java - 尝试将文件加载到 hdfs 时出错

Question

这种将文件加载到 HDFS 中的 java 方法一直对我有用，但现在，似乎存在一个与安全相关的错误，导致文件无法正确加载。

     Configuration conf = new Configuration();
     InputStream inputStream =
     new BufferedInputStream(new FileInputStream(localFilepath));
     FileSystem hdfs = FileSystem.get(new URI(HdfsURI), conf);
     OutputStream outputStream = hdfs.create(new Path(fileDestination));

尝试在上面第四行的 hdfs 中获取文件的位置时抛出错误：

    java.lang.IllegalAccessError: class org.apache.hadoop.hdfs.web.HftpFileSystem cannot access its superinterface org.apache.hadoop.hdfs.web.TokenAspect$TokenManagementDelegator
